About the Georgian Bay Biosphere

The United Nations Educational, Scientific and Cultural Organization (UNESCO) designated eastern Georgian Bay and the 30,000 Islands as a world biosphere reserve in 2004. Stretching 200 kilometres from the Severn River to the French River, it contains the world’s largest freshwater archipelago, as well as habitat for many species at risk. There are currently 18 biosphere reserves in Canada and more than 600 worldwide.

The Georgian Bay Biosphere (GBB) is a registered charity that works to protect the environment, create vibrant communities and support a healthy economy. Working with many partners across the region, the GBB relies on grants, members and donations to achieve its mandate of conservation, education and sustainable development.

Love Your Bay, Join Us Today!

The Georgian Bay Biosphere is situated in the traditional territory of many nations including the Mississaugas of the Credit, the Anishnabeg, the Chippewa, the Haudenosaunee and the Wendat peoples, and is now home to many diverse First Nations, Inuit and Métis peoples.

We acknowledge the United Nations Declaration on the Rights of Indigenous Peoples and celebrate Indigenous languages within the Georgian Bay Biosphere.


The biosphere reserve is an umbrella organization under which scientists, researchers, citizens and community groups work together on conservation efforts. This collaboration makes programs more effective and leads to better decision-making.

Parks & protected areas within the biosphere reserve give us places from which to monitor environmental changes over the long term. This information gathering, along with our work with area municipalities and First Nations, helps us identify opportunities to protect biodiversity. The GBB’s conservation work also supports research and training, including species at risk education since 2008.


Our Cultural Advisory Circle shares Indigenous perspectives and builds a network of groups across our diverse communities. We support Indigenous language revitalization through youth, elder and community activities. We are honoured to participate in powwows and other cultural ceremonies, and we are learning how to put reconciliation into action.


Education (for all ages) is at the heart of the GBB’s work. Planting vegetable and butterfly gardens, counting bugs and birds, water testing and restoring habitat, promoting cycling and trails—these are all the work of a community-based biosphere reserve.

Working with schools throughout the region, we support getting students outdoors. Our Lessons in a Backpack program, for example, encourages the use of school grounds for nature education. Lessons for grades one to nine provide local learning resources and field trips. And high-school students organize our annual Children’s Water Festival, which shows Grade 5 students the importance of water. You can learn more at gbbr.ca/education.

Kids in the Biosphere activities are designed for families interested in learning more about Georgian Bay. The Best for the Biosphere plant list teaches people how to provide habitat for wildlife. And our Life on the Bay guide is for property owners interested in reducing their environmental impact.

Sustainable Development

Sustainable development can only be achieved by working with other groups and organizations committed to the same goals. We encourage use of the best science and knowledge to create sustainable jobs, manage our resources, generate clean energy and support biodiversity.

For example, we network with other groups to support food-security programs such as Community Gardens and Community Kitchens, which help people connect socially while providing local, healthy and affordable food. Active-transportation initiatives support safe walking and cycling routes, making communities less reliant on fossil fuels.

Finally, we celebrate our UNESCO designation through our Amazing Places program, which showcases our unique landscape. You can learn more about these important areas within the biosphere at visitamazingplaces.ca.

A Gem in the Great Lakes

The Georgian Bay Biosphere is a globally unique freshwater archipelago of islands, acting as a natural corridor for species movement across land and water. Relatively few roads and lower development have made this region an important place for species conservation. However, with more local development, expanding road networks, the spread of invasive species and climate change, our biodiversity is at risk.
